I think when you don’t dream it doesn’t mean you don’t dream it more means you don’t remember them. I believe I remember reading something about that years ago.
That's true. Alcohol and other mood altering substances decrease ones ability to remember their dreams.
That's the case. You usually remember a dream because you woke up while it was in process. If you don't dream it means you're probably not entering REM sleep, which can have other indications.
